Abstract:

Variables` annotations in over-constrained problems are proposed and described in order to express preferences for optimal solution selection using preferences on variables. The basic interpretation of variables` annotations is presented and correspondence with hierarchical CSP and possibilistic CSP is described. An algorithm for solving systems of constraints with variables` annotations using mappings to hierarchy is designed. The potential application areas are also mentioned.
